All in all, this is one of the major annual projects for my team and I'm super excited to share it with you all. Happy to answer any questions, hear feedback, or suggestions for next year's report in a thread here or a DM.

We've made a heap of changes to our accessibility metrics, including under-the-hood changes to our Platform Access metric which takes into account where we do (or don't!) have redundancy for elevators or where a single elevator serves >1 platform. Blog post for that one is coming up, so stay tuned.

It's the first to include the changes from the 2024 Service Delivery Policy update. We made tweaks to our measures, using new and better data sources, and better reflecting rider experiences (for example, we now penalize dropped trips).

This year's SDP Report implements our new reliability metric, Excess Trip Time. We're really excited about this one because you can see how it shows the degradation of service and the result of the work to address problems. Blog post for more info www.massdottracker.com/latest-posts...

They did exactly this last week on transportation funding, a trial balloon.
Froze all IIJA / IRA funds. Then issued guidance claiming that's not what they meant & the civil service hysterically overreacted.
AASHTO bought it uncritically.

AASHTO Journal - Transportation Funding Restored After Inadvertent Suspension
An executive order issued by President Trump aimed at rolling back “Green New Deal” spending on renewable energy and electric vehicle programs ended up temporarily suspending all highway reimbursement payments to states for roughly four hours on January 21 due to a misinterpretation of the wording of the order.

Are places with bad pavement spending more because they have bad pavement? Are places spending little because they have less maintenance or reconstruction to do?
I doubt that explains everything and some time series variant would help get at that, but it's something one needs to consider.

I do have some direction of causality questions about this.
Putting aside all of the (really important!) questions about the nature and efficacy of policing... There is sort of a canonical example in economic modeling where the correlation between crime and number of police is similarly muddled.

Totally not the point and likely something someone coded years ago for some mild mannered fun, but isn't I kind of weird they suggest a hashtag for your announcement of your departure?

My take during my 2020s re-watch/watch (moved somewhere without upn during the original run) was that was that the g*m*rgate folks didn't spring out of nowhere in the 2010s, they were shitty people mad at VOY and spiked the discourse.

Like they can be a really nice rule of thumb tool, but the idea that if we just college enough SPFs then we'll know all the things is... Rough.
For a horrible afternoon, try having someone with a stats background read documentation about SPFs.

Cmfs really walk the border between useful statistical inference and massively over fit numbers that are treated as mysterious sources of Truth with no real underpinning

To what degree is this a function of the state legislature killing the Urban Partnership Agreement program in 2008ish? I imagine a lot of local decision makers are reacting to that experience.
